Rifabutin Therapy for the Prevention of Mycobacterium Avium Complex (MAC) Bacteremia in AIDS Patients With CD4 Counts = or < 200: A Double-Blind, Placebo-Controlled Trial

June 23, 2005 updated by: Pharmacia
The primary objectives of this trial are: To compare the safety of oral rifabutin versus placebo in the treatment of Mycobacterium avium complex (MAC) bacteremia in AIDS patients with CD4 counts less than or equal to 200 cells/mm3. To investigate the incidence of MAC in these patients. A secondary objective is to compare clinical response, quality of life (Karnofsky), and survival between these two groups.
